Replacement Windows in Texas

Current incentive status, energy-code requirements, and local market research for Texas homeowners replacing windows and doors.

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

Texas accepted IRA rebate funding but program rollout has lagged; check the State Energy Conservation Office for current status before counting on it.

  • Utility efficiency programs (Oncor service area). Oncor and other Texas utilities fund weatherization and efficiency incentives through participating contractors; window measures are typically part of whole-home packages. (Oncor / TX utility program pages)

Energy code

Texas adopts the IECC statewide with amendments; coastal counties add TDI windstorm certification requirements (WPI-8) that affect window product choice and insurance eligibility.
